Missed Dosages of Zoloft

hi everyone! so ive been on zoloft for 3-4 years. i was prescribed it for severe anxiety. im currently taking 100mg. i thought my life was going good and since school ended for me taking them wasnt a big priority to me. i think since june ive missed about 1-3 doses a week of it. but now, im having a horrible anxiety episode where i feel the need to confess things and if i dont confess them i feel i wont get better. ive had these episodes before i went on zoloft but idk why im having them now. idk if its because of my inconsistent use or that i snapped because whats bothering me now never really bothered me before. im on day 6 of consistently taking them and its pretty rough. im not sure if anyone else has also experienced this because this is all so painful, like i feel so depressed. advice would be nice:)
